Tigers Guma and Sangha were born in the primeval forests of Indochina. They were carefree in their childhood, but the ancient caves here attracted a group of Western expeditions. They shot their father. The unfortunate Guma was carried away by them, leaving Sangha and his mother to escape in a panic. Guma was sold to a circus and was forced to practice tricks such as jumping through fire rings every day. He missed his family and was not used to being domesticated, so his situation was very sad. His brother Sangha also could not escape the fate of being captured by humans. Fortunately, the chief's son loved it very much and kept it at home to live with him, saving him from a bumpy life. However, it was a wild tiger after all. When the family discovered the signs of danger, poor Sangha was sent to the zoo. A few months later, a tiger fighting competition began. The two brothers were unexpectedly arranged to be opponents in the arena. This reunion made the brothers overjoyed and began their escape plan.
